Question

Which of the following is a variable?

• A. Number of days in a week
• B. 5
• C. Temperature of a place in a day at different times
• D. Number of months in a year

Answer 1

Answer: (C)

Temperature of a place in a day at different times

The temperature of a place in a day at different times will be different. So it is a variable.

The number of days in a week and the number of months in a year always remain the same. So these are constants.

5 has a fixed value. So it is a constant.
